CCSS.6.EE.A.3

Expand the expression and combine like terms if possible.

-(1/4)(x + 16)

• -(1/4)x - 4

• (1/4)x + 4

• -(1/4)x + 4

• (1/4)x - 4

CCSS.6.EE.A.3

Expand the expression and combine like terms if possible.

-(1/5)(-x - 35)

• (1/5)x + 7

• -(1/5)x - 7

• (1/5)x - 7

• -(1/5)x + 7

CCSS.6.EE.A.3

Expand the expression and combine like terms if possible. (2/3)(x + 18 - 2x)

• (2/3)x + 12 - (4/3)x

  = -(2/3)x + 12

• (2/3)x + 12x - (4/3)x

  = (2/3)x + 12x

• (2/3)x + 18 - 2x

  = (2/3)x + 16x

• (2/3)x + 18 - (2/3)x

  = 18

CCSS.6.EE.A.3

Expand the expression and combine like terms if possible.

(3/4)(16x - 27 - 1)

• 12x - 21

• 12x - 28

• 12x - 18

• 9x - 21

CCSS.6.EE.A.3

Expand the expression and combine like terms if possible.

-12((5/6)x - 5) + 2x

• -10x + 60 + 2x = -8x + 60

• -10x + 60 + 2x = -12x + 60

• -10x + 60 + 2x = -8x - 60

• -10x + 60 + 2x = -12x - 60

CCSS.6.EE.A.3

Which of the following expressions are equivalent?

4(x - 3)

6x - 2(x - 3)

x + 3(x - 2) - 6

• 4(x - 3) and

  6x - 2(x - 3)

• 4(x - 3) and

  x + 3(x - 2) - 6

• 6x - 2(x - 3) and

  x + 3(x - 2) - 6

• All three expressions are equivalent
